Network executives took a blast: "They look like a bunch of milquetoasts, but in private you never saw such a bunch of raptors," the letter states.

"Nothing makes these guys happier than the failure of their friends," the letter continues -- before detailing a story of a bunch of "friends" in the business making a late-night bet to see who could be the first one to tell another exec that he had been fired.

"The guy who won reached the victim at sunrise," according to the letter. "That winner, by the way, was himself hosed from his network job a couple of years later."

As for studio heads: "They make the network suits look like the Dalai Lama.
